Application of anaerobic digester effluent as a fertilizer for vegetation

Abstract

The agricultural industry includes dairy, slaughterhouse, poultry and farms, is considered an important contributor to the national economy and GDP in Palestine. This projected aimed at investigation the best way of using digested cow manure as biofertilizers in growing squash plants in tunnel mulching. The production of the crop with organic fertilizer plays a vital role in organic agriculture today, cow farms produce large amounts of manure which contain a high content of organics, nitrogen, potassium and phosphorus .Cow dung is a primary source of plant nutrients and has been used as fertilizer for a long time. Cow manure was taken collected from Al-Jebreni cow’s farm in Al-Dahriah, Hebron governorate, Palestine. The farm has established anaerobic digester which ferments the manure in to liquid and solids bio-effluents. The experiment consist of 3 treatments (Solid, liqufied and control), and each treatment has 5 replicate laid out in a randomized complete block design. This study was implemented in Al-Dahriah city, Hebron governorate. Through the measurements made on the seedlings, it was found that the growth was faster in the seedlings of liquid digester, and the amount of production is greater than the other two types of treatments.
